If you want to build or test AI apps locally on Windows, start with a small stack: a current Windows version, Python, Git, VS Code, the right GPU driver, and one runtime such as PyTorch or ONNX Runtime. You do not need WSL for every project, [and for many Windows-first](https://www.winsolvetech.com/first-steps-new-pc/) apps, native development is the simplest place to start. Use WSL2 only when your tooling is clearly Linux-first, or move to a cloud dev environment when local hardware is not enough.

## What you need before you install anything

[Start with a Windows](https://www.winsolvetech.com/built-in-windows-tools-vs-third-party-utilities/) version that still gets current updates, because AI tooling changes fast and older builds tend to cause avoidable install problems. Windows 11 is the easiest target, and recent Windows 10 builds can also work for many setups.

You also want:

- A 64-bit CPU.
- At least 16 GB of RAM if you plan to run local models or train small ones; more helps a lot.
- Enough free disk space for Python packages, model files, and caches. AI tooling can fill a drive quickly.
- Administrator access, at least for the first install pass, so you can add drivers and set up system-wide tools if needed.
- A GPU if your goal includes faster local inference or training. NVIDIA is the most straightforward choice for many Python AI stacks because CUDA support is common. AMD and Intel can work for some workloads, but the runtime path is more specific.

If you already know you will use only cloud APIs and remote model hosting, the hardware bar is lower. If you want local testing, start with a machine that can handle the model sizes you expect to use. A setup that is fine for a small demo may feel painfully slow with a larger model.

You do not need WSL to develop AI locally on Windows. Install it only if your project, tools, or build steps actually need a Linux environment.

## The simplest Windows AI stack to start with

The leanest practical stack is: Windows, Python, Git, VS Code, your GPU driver, and one AI runtime such as PyTorch or ONNX Runtime. That gives you a path to write code, pull sample projects, install packages, and run a model locally.

Use this as your baseline:

- Python for the app and package management.
- Git for pulling sample code and working with repos.
- VS Code as the editor.
- Vendor GPU drivers, installed before you try to use acceleration.
- PyTorch if you plan to follow common Python model examples.
- ONNX Runtime if you want a lighter inference path or plan to run exported models.

Keep the first setup small. [Many Windows problems come](https://www.winsolvetech.com/set-up-ai-tools-windows/) from installing extra tools before the base stack is working. If you are not sure you need Docker, Conda, CUDA toolkits, or WSL2 yet, skip them until a project actually asks for them. A clean minimal setup is easier to verify and easier to repair.

## Install the core tools in the right order

Install in this order so each layer can find the one below it: GPU driver, Python, Git, VS Code, then your AI framework. That sequence avoids most PATH and detection problems.

1. Install the GPU driver first if you have a supported GPU. Use the latest stable driver from your GPU vendor. After the install, reboot if the installer asks. This matters because framework installs often check the driver when they decide whether GPU support is available.
2. Install Python from the official Windows installer. During setup, enable the option that adds Python to PATH.

```powershell
python --version
```

PowerShell

If that prints a version number, [Windows can find Python](https://www.winsolvetech.com/windows-11-automatic-updates/).

1. Install Git. Keep the defaults unless you have a team standard already. Git is what you will use to clone samples and manage your code.
2. Install VS Code. Then add the Python extension so the editor can find interpreters, lint code, and run notebooks if you need them.
3. Create a project folder and a virtual environment. This keeps package versions isolated per project.

```powershell
mkdir ai-local-demo
cd ai-local-demo
python -m venv .venv
.\.venv\Scripts\Activate.ps1
```

PowerShell

1. Install one runtime, not several at once. If you want a general Python stack, start with PyTorch. If your project is export-and-run focused, start with ONNX Runtime. Follow the official install command for your hardware path, because the exact package choice depends on GPU support and framework version.
2. Open the folder in VS Code. Confirm that VS Code is using the `.venv` interpreter, not a system Python install.

The key detail here is order. If you install the editor first, then change Python later, VS Code may keep pointing at the wrong interpreter until you switch it manually. If you install a framework before the GPU driver is in place, you may end up debugging a CPU fallback that looks like a broken GPU setup.

## Choose native Windows or WSL2 for your project

Stay native on Windows if your app is meant to ship on Windows, uses Windows-specific APIs, or mainly calls Python libraries that already support Windows well. Native development is also easier when you want to keep file paths, permissions, and the editor all in one environment.

Choose WSL2 if your project depends on Linux-first tooling such as shell scripts, build steps, or packages that are simpler on Linux. WSL2 is also a good bridge when your production environment is Linux and you want your local setup to behave similarly.

A simple rule helps here:

- Native Windows: Windows desktop apps, Office add-ins, local tooling, Python scripts, model inference with Windows-supported runtimes.
- WSL2: Linux build chains, container-heavy workflows, packages that document Linux as the supported path.
- Cloud dev environment: large models, shared team environments, or cases where your local machine does not have enough RAM or GPU memory.

Do not install WSL2 just because it sounds more advanced. If your project already works on native Windows, adding WSL2 can create extra file-sharing and path-conversion issues. On the other hand, if you keep hitting package or build errors that are clearly Linux-specific, WSL2 may save you time.

## Set up your first test project

Use a tiny project that proves three things: Python runs, a package installs, and your AI runtime can load a model or device. A hello-world script is not enough for this step.

1. Create a new folder and activate your virtual environment.

```powershell
mkdir ai-test
cd ai-test
python -m venv .venv
.\.venv\Scripts\Activate.ps1
```

PowerShell

1. Install a small test package. Pick the runtime you actually plan to use. If you chose PyTorch, install PyTorch for your target hardware path. If you chose ONNX Runtime, install that instead.
2. Create a test file named `test_ai.py`. Use a real import and a simple tensor or session check. For PyTorch, a basic CPU test is enough to prove the install first.

```python
import torch

print(torch.__version__)
print(torch.cuda.is_available())
```

test\_ai.py

1. Run the script. You should get a version string and a clear `True` or `False` for CUDA support.

```powershell
python test_ai.py
```

PowerShell

1. If you chose ONNX Runtime, load a small model or at least create a session with a known sample model. The point is to make the runtime do actual work, not just import cleanly.

If the script runs without import errors and you can see the runtime detect the device you expect, the environment is usable. If it fails here, fix the base stack before adding any larger project code.

## How to check that your GPU is actually being used

Do not trust a package install screen alone. A lot of AI code will happily run on CPU if the GPU path is missing, mismatched, or misconfigured.

Use quick checks like these:

- In PyTorch, `torch.cuda.is_available()` should return `True` if CUDA is set up correctly.
- In a training or inference script, look for the device name and make sure tensors or models are moved to the GPU.
- Watch Task Manager’s GPU view or your vendor’s monitoring tool while the script runs.
- For ONNX Runtime, confirm that the provider list includes the accelerator you expect, not only the CPU provider.

If the GPU is not active, check the most likely causes first: wrong driver, wrong framework build, unsupported GPU family, or a package that only installed CPU support. The hard part is that the code may still run and look fine. You need a positive device check, not just a successful import.

## The Windows gotchas that waste the most time

The most common Windows problems are boring, repeatable, and fixable if you know where to look.

- PATH issues: `python` or `git` works in one terminal but not another. That usually means the installer did not add the tool to PATH, or the shell has not picked up the change yet.
- Wrong Python version: your project may need a newer or older version than the one Windows found first. Use a virtual environment and make sure VS Code points at that interpreter.
- Permission problems: if package installs fail in a system folder, switch to a virtual environment and avoid installing into global Python unless you really mean to.
- GPU mismatch: the driver is installed, but the framework build does not match the hardware path. This is common when someone installs a CPU-only wheel and expects acceleration anyway.
- WSL confusion: a package installed in Windows Python does not automatically appear inside WSL2, and the reverse is also true. Treat them as separate environments.
- File sync and antivirus delays: large package installs or model downloads can appear to stall on managed machines. Sometimes the fix is just waiting; sometimes the machine policy is blocking the path.

If a setup fails, check one layer at a time. Start with `python --version`, `git --version`, and a simple package import before blaming the model code. That saves you from chasing the wrong problem.

## When this setup is enough and when to go bigger

This local Windows setup is enough for app prototyping, small-scale inference, API integration work, prompt testing, and experiments with modest model sizes. It is also a good fit if you are building a Windows desktop app that calls an AI model locally or remotely.

Move to a bigger setup when you hit one of these limits:

- Your model does not fit in local GPU memory.
- You need repeatable builds across a team.
- Your project depends on Linux-only tooling or container behavior.
- You need multiple GPUs or specialized accelerators.
- You want shared, disposable environments instead of a machine you must keep repairing by hand.

At that point, cloud GPUs, containerized dev environments, or a team-standard platform make more sense. The local Windows stack still stays useful as your editing and testing machine, but it stops being the whole solution.

## Conclusion

If you want the shortest path, build the base stack first, verify Python and Git, install one AI runtime, and test with a tiny project before you move on. That gives you a working local environment you can trust instead of a pile of tools that only look installed. Once that is stable, decide case by case whether the next project stays native on Windows, moves into WSL2, or belongs on a cloud GPU.

## Frequently Asked Questions

### Do I need WSL2 to do AI development on Windows?

No. Many AI projects work fine natively on Windows. WSL2 helps when the tooling is Linux-first or your production target is Linux, but it is not a requirement for every setup.

### Should I install PyTorch or ONNX Runtime first?

Install the one your project will use first. PyTorch is a common starting point for Python model work, while ONNX Runtime is a good fit for exported models and lighter inference paths.

### How do I know my setup is really working?

Run a small test project that imports your runtime and checks the accelerator path. A successful import is not enough; you want to see a model or tensor operation actually run, and you want a clear GPU or CPU result.
